It mainly comprises vacuum pump, moisture air filter,vacuum negative pressure tank and two filter trays with automatic drainage device to be provided to separate solids from liquids. The product is made by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

結(jié)構(gòu)簡(jiǎn)介

Structure

結(jié)構(gòu)：XTLZΦ260-Φ200型過(guò)濾機(jī)，設(shè)有兩個(gè)容量不同的濾盤(pán)，不同量的礦漿可以直接傾入相應(yīng)容量的盤(pán)內(nèi)進(jìn)行脫水處理。真空系統(tǒng)主要由旋片式真空泵、分水濾氣器、真空負(fù)壓罐、電磁閥以及真空管道組成。

1. Structure: XTLZΦ260-Φ200 filter has two filter  disks with different capacities. Slurry of different amount can be directly fed  into the disk with corresponding capacity for dewatering. The vacuum system is  mainly composed of rotary-vane vacuum pump, water-separating gas filter, vacuum  negative pressure jar, electromagnetic valve, and vacuum duct.

電控系統(tǒng)由控制面板及繼電器等元件組成其結(jié)構(gòu)原理見(jiàn)下圖：

The electric control system is composed of  control panel, relay, and other components. See the figure for its structure.

（1）Φ120毫米濾盤(pán)；（2）Φ240毫米濾盤(pán)；（3、5、7、9）電磁閥；（4）真空表；（6）液拉控制組件及真空負(fù)壓罐；（8）自動(dòng)排水閥；（9）分水濾氣器；（10）真空泵；（11）電動(dòng)機(jī)。

(1) filter disk with the diameter of 120mm; (2) filter disk with the diameter of 240mm; (3, 5, 7, 9) electromagnetic valve;  (4) vacuum meter; (6) hydraulic control assembly and vacuum negative pressure  jar; (8) automatic drain valve; (9) water-separating gas filter; (10) vacuum  pump; (11) motor

2、過(guò)濾原理：真空泵起動(dòng)后約10秒內(nèi)，可將真空負(fù)壓罐內(nèi)，抽成一個(gè)不小于91.2kpa(684毫米汞柱)的負(fù)壓腔，然后接通電磁閥3或5在壓力差的作用下，使濾盤(pán)內(nèi)的液體很快透過(guò)濾紙，達(dá)到脫水的目的。

2. Working Principle: Within around 10s  after the vacuum pump is started, make a vacuum capacity with the pressure of  not lower than 91.2kpa (684mm  mercury column) in the vacuum negative pressure jar. Then connect the  electromagnetic valves 3 and 5. Under the action of pressure difference, the  liquid in the filter disk permeates into the filter paper very quickly so that  the purpose of dewatering can be served.

3、結(jié)構(gòu)特點(diǎn)：

3. Structural Feature:

本機(jī)結(jié)構(gòu)簡(jiǎn)單、緊湊，真空系統(tǒng)工作可靠，具有較高的真空度，         為防止真空負(fù)壓罐內(nèi)的液體進(jìn)入真空泵，在器內(nèi)設(shè)置了上下接點(diǎn)，當(dāng)液體達(dá)到預(yù)定高度時(shí)真空泵自動(dòng)停車(chē)，同時(shí)打開(kāi)放氣電磁閥，待液體排完后自行起動(dòng)。

This machine features simple and compact  structure, reliable operation of vacuum system, and high vacuum degree.

To prevent the liquid in  the vacuum negative pressure jar from entering the vacuum pump, upper and lower  connection points are designed for this machine. When the liquid reached the  preset height, the vacuum pump stops working automatically. At the same time,  open the air-release valve. It starts up automatically after all the liquid is  discharged.
